How to enable wet cleaning on the robot vacuum cleaner Xiaomi: full instruction

Xiaomi vacuum cleaners are no longer just smart brooms — modern models are equipped with a wet cleaning function that allows not only collecting dust, but also washing floors at different intensity. However, many users face problems: the wet cleaning button is inactive in the application, the robot leaves divorces, then refuses to spray water. In this article, we will examine all ways to enable wet cleaning on Xiaomi, Dreame and Viomi robots – from basic settings to solving non-obvious errors.

It’s important to understand that the activation algorithm is model-dependent: the Mi Robot Vacuum-Mop 2 Pro has a different process than the DreameBot D9, and older versions (such as the Mi Robot 1S) can require additional accessories to clean, and we’ve compiled universal instructions and unique life hacks that you won’t find in the official documentation — like how to get around the restriction on simultaneous dry and wet cleaning or adjust areas with different levels of humidification.

What Xiaomi models support wet cleaning

Not all Xiaomi robot vacuum cleaners can wash floors, and the wet cleaning feature is available in the following series:

• 🔹 Mi Robot Vacuum-Mop (all generations: P, 2, 2 Pro, 2 Ultra)
• 🔹 DreameBot (D9, D10, L10, W10 newer)
• 🔹 Viomi V3 and V2 Pro (with a wet cleaning module)
• 🔹 Xiaomi MiJia 1C (requires the purchase of a separate water tank)

If your model is not on this list, but there is a water tank in the configuration, check the serial number on the official Mi Home website. Sometimes the manufacturer releases firmware upgrades that add wet cleaning support for older devices (for example, for Mi Robot Vacuum). 1T after updating to version 3.5.8_0040).

Note that some low-end models (such as the Mi Robot Vacuum E10) are marketed as “hybrid” but in fact only spray water manually – automatic humidification is not available for them.

Preparing the robot for the first wet cleaning

Before you turn on the function, you need to properly install the accessories and fill the robot, and errors at this stage will lead to the device either not spraying water or will start spitting out the liquid randomly.

Install a water tank (must click to the end)

Secure the wipe for cleaning (side with microfiber down)

Pour distilled or boiled water (not above the MAX label)

Check that the spray valve is not clogged (blow the holes)

Turn off the "Vacillier Only" mode in the settings-->

Pay special attention to the type of water. The manufacturer recommends using distilled or boiled water to avoid lime plaque on the nozzles. If you have hard water in your area, add a special tool for robot vacuum cleaners (for example, Xiaomi Mi Robot Detergent) to the tank, which prevents scale formation and improves the slip of the napkin.

Also check the condition of the napkin. If it is worn out (poor, holes), the robot will leave dirty stripes. The optimal rate of replacement is every 2-3 months during daily cleaning. For models with a vibrational mop (for example, DreameBot W10), use special wipes with attachments - conventional fabric will not work.

⚠️ Warning: Never put hand-cleaning detergents (such as Mr. Proper) in the tank, which foam and can damage the spray pump. Only use liquids marked "For robot vacuum cleaners».

How to enable wet cleaning through the Mi Home app

The main way to manage is through the official Mi Home app (or Dreame for the respective models). The interface may differ depending on the firmware, but the general algorithm is as follows:

1. Open the app and select your robot vacuum cleaner.
2. Go to Cleaning (or Cleaning in English).
3. Click on the icon “Wet Cleaning” (usually a faucet or drop of water is depicted).
4. Select the intensity level: 💧 Weak (for laminate and parquet) 💦 Medium (for tiles and linoleum) 🌊 Strong (for persistent pollution)

Start

If the wet cleaning button is inactive, check:

• 🔋 The level of charge of the robot (must be at least 20%).
• 💧 Water in the tank (the sensor may not work if the water is less than 50 ml).
• 📱 App version (upgrade to the latest in Google Play or App Store).
• 🔄 The state of the firmware of the robot (in the Settings section) → About the device).

For models with automatic mop lifting (for example, DreameBot L10 Ultra), an additional item will appear in the settings to Raise a napkin on carpets. Turn it on so that the robot does not wet the carpets.

💡

If the robot is not spraying water, try hand-blowing the nozzles with compressed air (such as a keyboard cleaner), often with lime deposits clogging the nozzles.

Setting up wet cleaning by zones and schedule

One of the most useful features is the ability to set different cleaning modes for individual rooms, for example, in the kitchen you can turn on intensive moisture, and in the bedroom you can only clean dry.

1. In the application, go to the Map and select the desired room.
2. Click Cleaning Settings (or Cleaning Settings).
3. Activate the option Wet Cleaning and set the spray level.
4. Save the settings and start cleaning.

To create a wet cleaning schedule:

1. Go to the Schedule (Schedule).
2. Add a new task and select days/times.
3. Turn on the option of wet cleaning and set the intensity.
4. Specify areas that need to be washed (or exclude those where cleaning is not needed).

In Xiaomi models with support for Yiko (voice assistant), you can configure voice commands such as “Wash the kitchen wet”, to do this, in the robot settings, activate the voice control option and link the device to Alice or Google Assistant.

⚠️ Note: If the robot starts to “lose” during zone cleaning (for example, skips rooms), update the room map. → Edit → Clean and resave. Then start the robot in training mode.

Solving Common Problems With Wet Cleaning

Even after the right setup, the robot can work incorrectly, and let's look at the typical errors and how to fix them:

1.The robot doesn't spray water

Causes and solutions:

• 🚫 The sprayer is clogged. → Wash the nozzles under running water or clean with a needle.
• 🔋 The battery sat down. → Charge the robot to 100% (some models block spraying at a charge level below 30%).
• 💻 Firmware failure → Restart the robot (hold the power button for 10 seconds) or update the software.
• 💧 No water in the tank. → Check the level sensor (sometimes it sticks - knock gently on the tank).

2 Robot leaves divorces

What to do:

• 🧼 Use special cleaning products for robots (they reduce foaming).
• 🧽 Wash the water tank after each cleaning (especially if you use hard water).
• 🧻 Wash the napkin after cleaning and dry it (wet cloth collects dirt worse).
• 🔄 Reduce the intensity of spraying in the settings.

3.Wet cleaning is not available in the appendix

Possible causes:

• 📱 An outdated version of the app → Update Mi Home to the latest version.
• 🤖 The robot is not tied to the account → Reconnect the device in the settings.
• 🔧 There is no water tank. → Install a tank (even if it is empty, some models require it to be in place).
• 📡 Problems with Xiaomi servers → Check the status of services on status.mi.com.

Compatibility with detergents and accessories

The manufacturer recommends using only original consumables, but in practice many users successfully use analogues.

• 🧴 Contain chlorine (corrodes plastic and rubber seals).
• 🫧 Form foam (can get into the engine and cause a breakdown).
• 🧪 Have abrasive particles (scratching a napkin and floor).

Safe alternatives to the original Xiaomi Mi Robot Detergent:

• 🌿 Eco-cleaners based on citric acid (for example, Ecover).
• 🧼 Liquid for parquets without wax (for example, Pronto).
• 💧 Distilled water + 1-2 drops of vinegar (for disinfection).

Microfiber fabrics with a density of at least 300 g/m2 are suitable for napkins. You can cut them out of old towels or buy universal ones for Swiffer. The main thing is that the fabric does not shed or leave a pile.

In vibratory mop models (like DreameBot W10), the napkin is attached to Velcros. Don't use long-pile fabrics, they'll clog the mechanism. The best option is loop-coated napkins (like Vileda mop).

💡

Using non-original detergents can void the warranty, and if the robot breaks down due to the "wrong" chemistry, the service center will refuse repairs.

Comparison of wet cleaning in different models Xiaomi

Not all Xiaomi robot vacuum cleaners are equally good at floor washing, and we tested several popular models and compiled a comparison table:

If you care about the quality of your washing, look for a vibratory mop (DreameBot W10 or Mi Robot Vacuum-Mop 2 Ultra) that is better at cleaning persistent contaminants, but more expensive. For smaller apartments, the Viomi V3 is cheaper, but requires manual change of modes on carpets.

Pay attention to water consumption. For example, the DreameBot D10 Plus consumes about 200 ml/hour at maximum intensity, and the Mi Robot Vacuum-Mop 2 Pro only uses 60 ml/hour. If you have a large apartment, choose a model with a water capacity of 300 ml.
